Abstract

The results of the mathematical modeling of a continuous biotechnological process for producing lactic acid are considered. The model is based on the Luedeking-Piret kinetic equation, which includes the concepts of the maximum specific rates of biomass growth, substrate consumption, and product formation. The possibility of the existence of optimum conditions for productivity with respect to the target product and the possibility of the existence of a multiplicity of steady states that ensure the same value of productivity are shown. An algorithm is described for calculating the characteristics of the process for different concentrations of a substrate in the inlet stream and different dilution rates.
